ELECTROMAGNETIC CONTROL DEVICE FOR EXI'IS OF SAND-BOXES.

Specification of Letters Patent.

Patented Nov. 17, 1914.

Application filed March 16, 1914. Serial No. 825,098.

To all whom it may concern Be it known that I, GEORGE ORBIN, a citizenof the United States, residing at Hoboken, in the county of Alleghenyand State of Pennsylvania, have invented certain new and usefulImprovements in Electromagnetic Control Devices for Exits of Sand-Boxes; and I do hereby declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same, referencebeing had to the accompanying drawings, and to the letters and figuresof reference marked thereon, which form a part of this specification.

This invention relates to new and useful improvements in sand boxes inwhich the exit end of the box is controlled by the movement of the coreof a solenoid which is actuated as the electromagnet is energized.

My invention comprises various details of construction, combinations andarrangements of parts which will be hereinafter fully described, shownin the accompanying drawings and then specifically defined in theappended claim.

1 illustrate my invention in the accompanying drawings, in which:

Figure l is a central vertical sectional view through a magnetic sandbox having features of my invention and Fig. 2 is a cross sectional viewon line 22 of Fig. 1.

Reference now being had to the details of the drawings by letter,'Adesignates a sand box mounted upon a suitable support C in which theexit duct C is formed. An electromagnet D is provided with areciprocating core E which, as the magnet is energized,

is adapted to be given a longitudinal movement. A slide F is fastened tothe outer end of said core and is movable within a slot formed in thestandard which supports the sand box and which moves transversely acrossthe exit duct which is adapted to control the same.

The operation of the form of my invention as disclosed in Fig. 1 will bereadily understood and is as follows: When it is desired to allow sandto be dispensed from the box, the current is sent through a coil of theelectromagnet, causing a longitudinal movement to be imparted to thecore and which has connected to its end the slide which regulates theexit duct or passageway leading from the box, thus allowing sand to bedispensed from the box.

\Vhat I claim to be new is:

A sand box apparatus comprising a hollow support having laterallyextending flanges at its upper end, said support being hollow andflaring near its upper end with a channel formed in the upper surface ofone of its flanges and leading into said flaring portion, the flaringpart of the support extending below the flanges, a hopper having acontracted exit end, the marginal wall of which exit end overhangs theupper flaring part of the support and provided with flanges which engagethe flanges upon the support, a solenoid having a sprang-pressed coreterminating in a slide, movable through said channel and having itsopposite edges and end beveled and conforming to and adapted to engagethe flaring wall of the support, the upper surface of said slide adaptedto contact with the under surface of one of the flanges at the bottom ofthe hopper and the under surface of the wall of the hopper whichoverhangs the flaring part.

In testimony whereof I hereunto ailix my signature in presence of twowitnesses.

GEORGE ORBIN.
